Abstract
The invention relates to a PH (Potential of Hydrogen) test paper card, which comprises a substrate (1), wherein a test paper area (3) and a colorimetric area (2) are arranged on the substrate; 14 unit test paper books are regularly arranged on the test paper area; a piece of plastic paper with the same size is attached to the back part of each piece of test paper in each test paper book, so that the next piece of test paper cannot be wetted when the former piece of test paper is used; 14 colorimetric cards are arranged on the colorimetric area; the colors of the colorimetric cards show the corresponding potential of hydrogen and are marked with corresponding numbers 1, 2, 3, ... 14; the number 7 is in a circle to show neutral. The PH test paper card is simple in structure, easy to operate, convenient to compare colors and obvious in effect.
Description
Technical field:
The present invention relates to chemical reagent field, relate in particular to pH test card.
Background technology:
Solution is the important content of courses of in middle school chemistry class teaching material, and usually need the potential of hydrogen measuring solution, traditional pH test paper defect is how not handy.
Summary of the invention:
The object of the invention is open a kind of structure simple, colorimetric solution acid alkalinity test easily paper card.The technical scheme that the present invention goes out for achieving the above object is:
The present invention includes substrate (1), substrate is provided with test paper district (3) and colorimetric district (2) said test paper district and fitly arranges 14 unit test paper originally, each test paper in this each test paper below with one and its plastic paper of a size, during use, unlikely invading is wet on next; , there are 14 colorimetric cards in said colorimetric district, the potential of hydrogen corresponding to the display of the color of each colorimetric card, and indicate corresponding numeral 1,2,3 ... 14, wherein 7 in circle, is neutral.Structure of the present invention is simple, processing ease, and colorimetric is convenient, successful.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention, 1 substrate in figure, 2, and colorimetric district, 3 test paper districts.
Embodiment:
Below in conjunction with drawings and Examples, the present invention is further elaborated:
See accompanying drawing, the present invention includes substrate (1), substrate is provided with test paper district (3) and colorimetric district (2) said test paper district and fitly arranges 14 unit test paper originally, each test paper in this each test paper below with one and its plastic paper of a size, during use, unlikely invading is wet on next; , there are 14 colorimetric cards in said colorimetric district, the potential of hydrogen corresponding to the display of the color of each colorimetric card, and indicate corresponding numeral 1,2,3 ... 14, wherein 7 in circle, is neutral.
Structure of the present invention is simple, processing ease, and colorimetric is convenient, successful.
